' AUGUST W. DENOW, OF OSHKOSH, WISCONSIN.

STORM-WINDOW OPERATOR.

Specification of Letters Patent.

Application filed June 27, 1919. Serial No. 307,067.

To all whom it may concern:

Be it known that I, Aueus'r W. DENOW, a citizen of the United States,residing at Oskkosh, in the county of Winnebago and State of Wisconsin,have invented certain new and useful Improvements in Storm- WindowOperators; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple andinexpensive, yet a highly efiicient and in every way desirable devicefor opening storm windows simultaneously with either the lowering of theupper sash or raising of the lower sash of the ordinary window, and withthis object in view, the invention resides in the novel construction andarrangement hereinafter described and claimed, the descriptive matterbeing supplemented by the accompanying drawings.

Figures 1 and 2 are vertical transverse sections through a windowequipped with a storm sash and the improved operator for the latter,showing different positions of.

parts.

Fig. 3 is a horizontal section on the plane of line 3-3 of Fig. 1.-

Fig 4 is a fragmentary elevation illustrating the manner of attachingthe operating rods to the-sash.

Fig. 5 is an enlarged vertical section on the plane indicated by line 55of Fig. 3.

Fig. 6 is a detail perspective of a portion of one of the tracks and theslide mounted thereon.

In the drawings I have shown a common form of window frame 1, upper andlower sashes 2 and 3 mounted slidably in said frame, and a storm sash 4in the outer part of said frame, hinged thereto at 5. These parts are ofwell known construction and form no part of the present invention exceptin their association with the features described below.

I secure vertical tracks 6 to the'sash 4, mount a slide 7 on each track,connect the slides with the upper sash 2 by rods 8, and similarlyconnect said slides with the lower sash 3 by rods 9, both ends of allrods being pivotally mounted. By this arrangement, when either the upperor the lower sash is opened, the rods 8 and 9 will swing the storm sash4 outwardly as seen in Fig. 2,

the slides 7 then traveling along thetracks 6. The storm'sash is openedin proportion to the amount which the ordinary Window is opened and iscontrolled by either sash of the latter. I

The tracks 6 are by preference formed of metal stamped into L-shape intransverse section with one flange secured to the sash 4 and the otherflange beaded at 10, and although the slides 7 could be of any suitableconstruction, I prefer to stamp them from sheet metal, each slide havinga tubular body portion 11 and a lateral flange 12 extending therefrom,said flange being provided with openings in which the buter endsPatented Nov. 25, 1919., i

of the rods 8 and 9 are pivotally mounted.

I prefer to provide the inner ends of the rods 8 and 9 with balls orother heads 13 receivable in sockets 14 stamped at the center ofattaching plates 15 which are secured to the upper and lower sashes,said plates being also stamped to form slots 16 leading from the sockets14 to allow the rods 8 and 9 to fold rather flat against the sashes.

The details shown and described are preferable on accountof their simpleand inexpensive nature, but it will be obvious that other constructionsshould be followed within the spirit ofthe invention as claimed.Furthermore, although I will in most instances provide two operators foreach storm sash, located one at each edge of the latter, one suchoperator might well be used if desired.

1 claim:

1. The combination with a window frame having upper and lower slidingsashes and a hinged storm sash; of a track secured to said storm sash, aslide on said track, and rods connecting said slide with the upper andlower sashes respectively.

2. A storm sash operator comprising a track for attachment to the stormsash, a slide movable along said track, a pair of rods pivoted at oneend to said slide, and means for pivotally connecting the other ends ofsaid rods to the upper and lower sashes of an ordinary window.

3. A storm sash operator comprising a track adapted for attachment tothe storm sash, said track having .a beaded edge, a stamped metal slidehaving a tubular portion movable along said beaded track, said slidebeing provided with a flange stamped laterally from said tubular portionand provided with spaced openings, a pair of rods having one endpivotally mounted in said openings, and means for pivoting the otherends of said rods to the upper and lower sashes of an ordinary Window.

4. A storm sash operator comprising a' track for attachment to the stormsash, a

slide movable along said track, a pair of rods pivoted at one end tosaid slide andhaving heads on their other ends, attaching 10 platesadapted to be secured to the upper slots being provided leading fromsaid sockets to permit folding of said rods toward the sashes.

In testimony whereof have hereunto set my hand.
